Objectives: To examine whether the introduction of intermittent standing bouts during the workday using a height-adjustable workstation can improve subjective levels of fatigue, musculoskeletal discomfort and work productivity relative to seated work. Methods: Overweight/obese office workers (n=23; age 48.2±7.9 years, body mass index 29.6±4 kg/m2) undertook two, 5-day experimental conditions in an equal, randomised (1:1) order. In a simulated office environment, participants performed their usual occupational tasks for 8 h/day in a: seated work posture (SIT condition ); or interchanging between a standing and seated work posture every 30 min using an electric, height-adjustable workstation (STAND-SIT condition). Self-administered questionnaires measuring fatigue, musculoskeletal discomfort and work productivity were performed on day 5 of each experimental condition. Results: Participants' total fatigue score was significantly higher during the SIT condition (mean 67.8 (95% CI 58.8 to 76.7)) compared with the STAND-SIT condition (52.7 (43.8 to 61.5); p
